Thought I'd share what I wrote to Scott..
We've got several units out there, but I really don't have a handle on actual yields as yet. I do have high expectations, though. So far reliably, we've had no issues. Even have a client who runs a bunch of envelopes with no cutting into the master, another benefit of its thickness. Haven't done much color work, possibly due to the limited standard colors. I heard a rumour that Ricoh was trying to see if they make this Seri compatible. We'll see. For the price point this is a great box. I expect to see a drop in JP5500 sales, due to this. The only drawback I can see is that it's not Type 80 compatible. The type 40 does do a wonderful job, so maybe not a big deal. But, I do not like the UC's, so.....
